The Big Second Date

Oval Office kissed his way up Rainbow Dash’s neck, sliding himself slowly into her. Throwing back her head, she groaned out a long “ohhh…” that grew louder the deeper he got - and eventually she went from moaning out“oh” to moaning out “Ovallll…”

“Dash,” whispered Oval Office, “Your body is amazing… I mean, it was amazing before, but now it’s… you’re beyond amazing, Dash.”

“Oh, dude…” Dash moaned, reaching her hands down to grope Oval’s ass, “You really get me, Oval. You get that I’m fuckin’ awesome…” She kneaded his glutes with her fingers, pulling him deeper into her each time he thrust. “And you… mmph, you were cute before, but now… now you’re tall and strong and you got a big cock…”

Oval was intensely aware of the size and length of his dick; before Dash had “infected” him with her magical growth, he’d gotten used to being average - but now he was huge. His body was taller and stronger, but his dick had grown more than the rest of him. Yesterday, when he and Rainbow Dash had grown, his dick had ended up over a hundred feet long - a tall, throbbing tower of dark blue flesh. It had felt incredible to be that big, to live and to fuck at that size. And while his body wasn’t toppling buildings anymore, he was still big all over - and the cock he was sliding into Dash’s pussy was twelve inches long and nearly as thick as his wrist.

And Dash was big enough to take it, with a pussy that embraced every inch of him with its strong, slick walls. Even before her growth, back when she’d had her track-and-field physique, he’d admired her from afar. He’d watched her in motion, her hair flowing like a rainbow waterfall, her muscles glistening with sweat, and he’d found her beautiful back then.

But overnight, her body had grown taller and stronger and her curves had rounded out enormously. Her slender rear end had ballooned into a perfectly round bubble, and her A-cups had become… F-cups, maybe? They were huge, at any rate, and the growth spell’s magic made them impossibly firm, supporting themselves beautifully with no need for a bra. With the aid of the magic spell, she’d blossomed into the perfect woman - and when the spell made her grow into a giantess, she’d been better than perfect.

Of course, it had resulted in kind of a lot of property damage. But now, with his dick deep in Dash’s pussy and her hands groping at his back, it all felt worth it. Still thrusting, he lifted his upper body to get a better look at her. Her mouth was wide open and moaning, her face flushed, her rainbow bangs falling over her sky-blue skin. Her tits were jiggling with every bed-shaking thrust that Oval Office drove into her - and the sight of it made him thrust harder, making the bed beneath them rattle violently.

Oval reached down and placed his palms over her breasts, squeezing the soft, smooth flesh. Her boobs were far more that a handful, too big to ever get his fingers around. All he could do was squeeze harder, sinking his fingers into those beautiful blue mounds. Dash moaned at his touch, her pussy clenching as Oval massaged the sensitive flesh of her tits. God, she was beautiful, even more so when they were making love. He could barely take his eyes off her body…

But for a moment, he did take his eyes off her body - and it was probably a good thing, because he noticed that the first time that his bedside table was farther away than it should have been. Farther away and smaller. And turning his head revealed more alarming details: the ceiling was slowly growing closer, and his and Rainbow’s legs were extending off the end of the bed, almost long enough that the soles of their feet brushed the wall.

“Dash,” he groaned, “Dash, we’re growing again…”

Dash, whose eyes were shut tight, didn’t treat this news with the seriousness it deserved. “Aw, yeah,” she whimpered, “Let’s grow, Oval. Get big inside me, go deep with that giant dick, make my tits grow bigger and bigger… I wanna grow with you til our fuckin’ makes earthquakes…”

Dash’s words made Oval’s cock surge and his head swim. It felt so good to get bigger, and Dash liked it too… He wanted to share another giant-sized climax with her, to thrust a hundred-foot-long cock into her immense womanhood and feel those powerful muscles throb around his cock as he released gallons of cum.

He just barely convinced himself not to give in… but he couldn’t stop. His hips were almost moving on their own; his body wanted this. Not just to cum, but to grow again. “Dash, we’re growing,” he repeated, “we’re really growing, we’re gonna break my bedroom…”

At that moment, something did break - not the bedroom, but the bed, which collapsed noisily underneath them. Dash’s eyes snapped open, and she looked around the room, seeing the same warning signs that Oval Office had. “Oh, shit,” she muttered, “we’re really growing, but… fuck, dude, don’t stop. I don’t care how big we get, if I don’t cum I’m gonna die…”

“I can’t stop,” gasped Oval. “I don’t want to destroy my house, but I wanna cum and I wanna be big with you…”

“Me too, babe,” groaned Dash.

Oval fought to keep himself under control. He couldn’t stop himself from fucking Dash, but maybe he could get some help… “Dash,” he said, “Can you… call Twilight? Maybe she can help…”

Dash turned her head and shouted to her phone, voice-activating it to call Twilight - but after four rings with no answer, Dash groaned and hung up. “Uh, maybe Sunset?” suggested Oval, and Dash - somewhat reluctantly - tried Sunset Shimmer.

After a couple rings, Sunset picked up, muttering into the phone. “Dash?” she said, “I’m still mad at you, but if you’re calling because you’re having magical problems, then…” the line was silent for a while. “Are you fucking?”

Dash and Oval weren’t trying to make noise, but they couldn’t help the moans that escaped their mouths as pleasure overloaded their growing bodies. Nor could they help the creaking of the ruined bed and the overburdened floor beneath them as Oval thrust into Dash.

“Yeah,” said Oval. “But it’s making us grow again… and we can’t stop…”

“You can’t stop?” said Sunset. “Well, I mean… if you can stop, then definitely stop. But if you literally can’t stop, then I guess just try and finish quickly. And don’t fuck again. I’ll be right over.”

“You heard her,” said Rainbow Dash, stroking the small of his back. “You gotta finish it. Gotta make me cum or I’ll never stop growing…”

Oval started to thrust faster, driving his cock deep into Rainbow Dash. He could tell Dash was close - but if he wanted her to cum now, he needed to go hard and deep, overwhelming her love tunnel with sensation. Her pussy was sensitive, highly responsive to the right touch, but her body demanded a lot from a lover. Luckily, Oval Office had the strength and size to give her what she needed.

Each thrust made the floor creak and groan as their growing bodies put more and more mass on it. Their feet were up against the wall now, and they bent their knees to keep from busting through. Oval could feel his back hitting the ceiling every time he lifted his body, and he knew there wasn’t much time left. “Dash,” he moaned, “We’re getting too big, I don’t know if I can finish fast enough… I think we’re gonna keep getting bigger…”

And those words - the tantalizing prospect of outgrowing another bedroom and bursting, naked, into the night air - was what drove Dash over the edge. Squirming beneath him, whimpering and then crying out as her climax built in her core and exploded outward into her massive body. There was a final surge of growth, enough that the heels of her feet dented the walls - and then her body, still cumming, stopped growing.

With Dash taken care of, Oval still had himself to worry about - and with short, quick thrusts inside Dash’s spasming cunt, he brought himself to the brink, until his balls tightened and his climax went off like a rocket. His body tensed, and his cock unloaded rapid bursts of thick seed, pumping a giant-sized load into Rainbow Dash. He felt a brief surge of growth, putting his back against the ceiling… but he could tell he’d stopped growing.

“Okay, sounds like you two finished up,” said Sunset, over Dash’s phone. “You still growing, or…”

“Uh...” said Oval, “I thought you hung up. Didn’t you say you were gonna get here soon?”

“Well yeah,” said Sunset, “I’m driving now. Speakerphone. So… growing? Not growing?”

“We stopped growing,” said Oval. “But we’re too big to leave the room… and we can barely move…”

“Okay, we can work with that,” said Sunset. “Just don’t fuck again, okay?”

“No promises, Sunny,” said Dash playfully. “Oval’s still inside me, and it feels good.”

Sunset groaned. “Dash?” she said, “I know I don’t, like, completely have the moral high ground when it comes to not abusing magic. But I’m pretty mad at you for stealing my book and ignoring my advice. Can you just do the right thing and not fuck for like ten minutes?”

“Yeah,” Rainbow Dash muttered. “I was just kidding, Sunset. I’ll be good.”

“Awesome,” said Sunset. “Later.” She hung up, and Dash sighed, lying back against the ruined bed.

Oval wiggled hips hips, trying to gradually work his dick out of Rainbow Dash. His and Dash’s bodies took up almost the entire bedroom, and his butt was already close to the ceiling, leaving him very little space to maneuver. Slowly - and thanks in large part to his dick going soft - he managed to pull his cum-slicked cock out of her pussy. She sighed as pulled out - and it wasn’t a sigh of relief or of pleasure. Her face was pensive, distracted.

“Are you okay?” asked Oval Office.

“Yeah,” said Dash. “But Sunset’s right to be mad at me. I mean, messing with magic got me this rockin’ body and an awesome boyfriend, but it was selfish, and I tricked Sunset and Twilight… it could have gone really bad.”

“Well,” muttered Oval, almost too low to be heard, “We did do like millions of dollars of property damage-”

“It could have gone so bad,” said Dash. “I put my friendships at risk, and… I really owe her an apology.”

“Well… Sunset knows how important forgiveness is,” said Oval. “I think you know the difference between right and wrong, Dash. You just have to… not let anything get in the way of that.”
“Well, I’ve got you,” said Dash, “And I’ve got this body… I don’t think there’s anything else that’ll tempt me to abuse magic for a while.”

With some careful movements, the two of them shifted their bodies. From his position on top, Oval lowered himself onto the floor beside Rainbow Dash. With nowhere to go and nothing to do, they spooned atop Oval Office’s smashed bed, embracing in a bedroom that their increased size made extremely cozy.

And - a little sooner than expected - Sunset Shimmer came through the bedroom door. It just so happened that Oval Office’s ass was the closest thing to the doorway - and Sunset, intending to just take a couple steps into the room, walked straight into his bare buttcheeks.

“Sunset?” said Oval, looking at her over his shoulder. “You okay back there?” He felt Sunset’s tiny hands pushing back against his glutes, slightly tickling his dark blue skin as she steadied herself.

“Yeah, I’m all right,” said Sunset. “I just wasn’t expecting your butt to be, like, right there…” Oval Office couldn’t help but notice that her hands were still on his skin, exploring the shape of the muscle beneath. She let out an appreciative whistle as she squeezed the firm flesh, whispering “Damn, this boy’s big…”

“Hey!” said Dash, turning her head to glare at Sunset. “Hands off my man, all right?”

Sunset stepped back, lifting her hands from Oval’s rump. “Sorry, sorry,” she said. “It’s just… your bodies, both of them, they’re… pretty remarkable.”

“Well… I owe you an apology too,” said Rainbow Dash. “You tried to warn me, and I ignored you, and… hey, wait a minute. How’d you get into Oval Office’s house?”

“Lockpicks,” said Sunset casually, as if it was the most natural and obvious answer. “So anyway, I have the same cure Twilight administered yesterday. And based on the formula she gave me, I should be able to give you the correct dosage…”

“Should?” asked Oval nervously.

Sunset took her smartphone from her pocket. “She actually wrote a little script where I can punch in your current height and it gives me the right dose.” She squinted at the two giants. “You’re a little bunched up, but… you’re both like ten feet tall, right?”

“Yeah, give or take,” said Dash.

Sunset fiddled with her smartphone, then took a bottle and two vials from her purse. She poured out two doses, eyeing the blue liquid carefully, then leaned her body against Oval Office’s shoulderblades and raised the vials. “Say ahh,” she said, and Oval and Dash opened their mouths. She poured a dose into each of their open mouths, and they swallowed the flavorless fluid.

“Uh…” said Oval Office, “Wouldn’t it have been better to give one of us the medicine and see if it was the right dose... before using it on the other one?”

“Hm, good point,” said Sunset. Then, shrugging: “Well, Twilight’s the methodical one, not me. Hopefully I measured it right.”

Oval and Dash, at the same moment, felt their heads swim. Most likely, it was a less powerful version of the effect they'd felt when Twilight had shrunk them down from skyscraper height. That dose had knocked them unconscious, but this smaller concentration just gave them a woozy feeling - and that was joined by the sensation of falling.

As it turned out, that was simply what it felt like to shrink. Growing had been intensely pleasurable, multiplying the sensations of sex and climax - but shrinking wasn't as fun. It didn't hurt or anything, but it didn't excite in the same way.

“Woah,” mumbled Dash, rising to her feet as she felt herself stop shrinking. She patted at her body, first feeling for muscle and then clapping a hand onto her tits and her ass. “Ahh,” she sighed in relief. “I'm still super sexy.”

Sunset rolled her eyes. But Dash was right: the modest dose of shrinking potion had reduced her to the height she'd been before she and Oval Office had started making love. North of six feet, with huge tits and a thick, round ass.

“Ooh, and Oval’s still a hunk, too,” she said, eyeing up her boyfriend as he stood up. “I was worried you'd put us back to, y’know… normal.” The way she said normal, resounding with hollow dread, struck a chord with Oval.

“Well… you know I would still love you, right?” said Oval, putting a comforting hand on her shoulder. “You had a really great body before all this…”

“No, yeah, I know,” said Dash. “I mean, we've been over this. You were cute as hell before you got all sexified by the magic potion. But after feeling what it's like to be big and sexy, I don't want to go back to being slim little Dashie with the bee-sting tits. Especially considering how good it feels to fuck in a body like this…”

“Well then, I've got bad news for you,” said Sunset. “That potion was…” she paused, frowning slightly. “By the way, feel free to put your clothes back on anytime you like.”

“Oh!” said Oval. “Right, yeah.” He found where he'd tossed aside his clothes and started dressing himself, and Dash followed suit.

“Anyway, bad news,” said Sunset. “What we've learned from this incident is that Twilight’s counterspell potion did not cancel out the effects of the original spell. You two are still growing when you have sex. And it's going to keep happening every time until we figure out a real cure.”

“Oh,” said Oval, pulling his socks on as he sat on his ruined bed. “Uh, how long is that going to take?”

“Hard to say,” said Sunset. “The original effect came from three spells infused into a liquid - which, by the way, was actually a really bad idea. Liquid infusion introduces volatility that can amplify and perpetuate effects in just this fashion. Twilight is learning quickly, but there's a lot she doesn't know about magic.”

“Well, don't blame Twilight,” said Dash.

“I don't,” said Sunset sternly. “At all. I still blame you, Dash.”

“Oh,” said Dash, her face falling. “Yeah, I guess I am the only other person you could really blame.”

Sunset sighed. “Look, I'm not asking you to feel bad,” she said, “but you do need to abstain from sex until Twilight and I have figured out a proper counterspell. If you fuck, you'll grow again, and we've already seen that you have a hard time stopping once you've started.”

“Well, we wouldn't start smashing buildings this time,” said Oval.

“No, that's just the thing,” said Sunset, “you might. One of the strength-enhancement spells in that potion is also designed to reduce inhibitions and dampen your reasoning skills. It was cast on soldiers on some old, brutal wars… the spell actually has kind of a fucked up history.”

Oval winced. “Well, that explains some things about how we… acted…”

“Yeah,” said Sunset. “Twilight and I will work on dispelling that effect too. It might take a while, but our cure should put you back to normal…”

Rainbow Dash raised her hand.

“Yes,” sighed Sunset, with a roll of her eyes. “You'll get to keep your extra-sexy bodies. I know you'd never shut up about it if I took that away.”

Rainbow Dash lowered her hand.

“Okay,” said Sunset, “I'll drive Dash home. And until we get you that cure… no sex, no masturbation. Honestly, I'd recommend the two of you keep some distance from each other. The less temptation you have to deal with, the better.”

Oval woke up the next day feeling refreshed. Despite its unexpected complications, his roll in the hay with Rainbow Dash had left him with a sunny feeling that nothing could take away. Even though he’d spent the night on a smashed mattress, he’d never felt better-rested.

And keeping his mind off sex was easier than he expected. His schedule didn’t put him in the same classroom as Rainbow Dash today, so the “temptation” that Sunset warned about was easy to avoid. He passed her in the halls a couple of times, and he couldn’t help but admire her body - but once she was out of his sight, he didn’t find it too hard to refocus his mind on school. He felt good about the way things were going.

After the last class of the day, he got Sunset’s cell number from Applejack and sent her a text. Hey Sunset, it’s Oval. Not trying to rush, but do you know when you and Twilight are going to have that cure?

Sunset’s answer came in under a minute. Hard to say. Heading to Twilight’s now. Could be ready tomorrow but prob not. You doing OK?

I’m all right, wrote Oval. Temptation wasn’t a problem today.

Another text popped up, this one from Rainbow Dash. hey oval, you know how in some movies a person will be talking on a phone and the person they’re talking to will be right behind them and it’s like, do the people who wrote this movie even know how phones work???

Oval raised an eyebrow, trying to interpret the text - and after a moment’s thought he turned around to find Rainbow Dash grinning behind her. “Hey dude!” she said - and she lowered her phone, giving Oval Office an unobstructed view of her chest.

“Hey Dash!” he said. “It’s great to see you, but… we probably shouldn’t hang around each other too much, right?”

Dash rolled her eyes. “I don’t know about you, but I felt fine today. I wasn’t all… growth-horny like I was while we were fucking. I think it’s out of my system for a while. I mean, don’t get me wrong, I’m looking forward to the next time you and I can fuck… but I can go without it for a while. How about you?”

Oval sighed. “Yeah, I feel okay too. As long as we stay out of each others’ bedrooms, I think we can hang out without causing any more catastrophes.”

“Awesome!” said Dash. “Are you starving? ‘Cuz I’m starving.”

“Wow, this was the perfect choice for our two-day-iversary,” joked Rainbow Dash, as the waitress set down her burger.

“Yeah, the same diner as our first and only date,” said Oval Office, smirking. “Looks like you’re not as hungry today, though. Just one burger this time?”

“Hey, I was a growing girl,” said Dash. “And growing, and growing…”

Oval chuckled. “Careful,” he said. “Too much talk like that, we might give in to irresistable temptation…”

“Yeah, we’re playing with fire here,” said Dash, keeping her voice low and casting a quick glance at the neighboring booths. “Who knows what might happen if I started talking about how big the two of us got… about the way I shook my giant tits in your face when I was growing right before your eyes…” She nibbled thoughtfully at a french fry, staring at Oval with mischief in her magenta eyes. “Do you remember how my pussy tasted, Oval? When you buried your face in it, licking up that warm, sweet pussy juice? If I had any doubts about you, the way you ate my mouthwatering cunt put them to rest…”

At first, Oval laughed off her seduction… but the longer she went on, the more it was starting to work. He did remember the taste of her pussy, and the memory gave him a hunger that the club sandwich on his plate would not satisfy. “Hey, c’mon, Dash,” he said, “take it easy on me, okay?”

“Oh no,” said Dash, licking her pale blue lips. “Am I tempting you? If I accidentally get you too horny, are you going to start growing right there in your seat? Mmm, I’d have to watch my handsome boyfriend busting out of his clothes… I’d have to see those lovely muscles ripping the seams of your shirt… and then the table would start to rise as your cock got big and hard underneath it…”

Dash’s body started to gyrate slowly in her seat, and one of her feet began to nudge at his ankle. “All the little people would run away... and we’d have the diner to ourselves, Oval. Your cock would be so big that I’d put my face right up to the tip and make out with it, slurping up a big mouthful of precum… ooh, and then I’d use my whole fuckin’ body to jerk that monster off. Slide my tits and my thighs up and down that beautiful blue shaft until you shot a load so big it coats the whole floor.”

Under the table, Dash’s bare foot crept up Oval’s leg, tickling his thighs as it came ever closer to his crotch. Oval knew he should stop her - but he was quivering, held in rapt attention by the fantasy Rainbow Dash was sharing with him. “And then it’s my turn to get big,” said Dash. “You’d pick me up and lay my little body down… and your pinky finger would be just the right size to fill my cunt. With just your littlest finger, you’d stretch me, you’d make me squirm… and then I’d start to get bigger. Pretty soon, you’d need two fingers to fill me up… then more… I’d be begging for your big cock the whole time, and once I was big enough… you’d give it to me.”

Her foot finally arrived at Oval’s crotch, and she gently pressed at his stiffening cock with the ball of her foot. The intimate touch made him gasp - but it also shocked him out of his trance. He jerked his body sideways, moving his crotch out of Dash’s reach, and met her eyes with a worried expression.

“Dash,” he hissed, “I know you’re just having fun, but… you’re kinda making this harder than it needs to be. I wasn’t having any trouble up til now, but… it’s gonna be hard not to jerk off tonight.”

“Geez, sorry,” said Rainbow Dash. “I’m… kinda not being a great girlfriend, am I?”

“No, come on,” said Oval, reaching his hand across the table to rest it on hers. “I know you’re frustrated by the no-sex thing, especially since our relationship has just gotten started. I’m frustrated too.”

“Yeah,” said Dash, slumping in her seat. “I’m glad you stopped me before I got any further, honestly. I was starting to get pretty horny too.” She rubbed her temple, ruffling her rainbow bangs. “Maybe I better just eat my damn burger.”

The rest of the meal was awkward, with both Dash and Oval afraid to say something that would constitute temptation. The threat seemed very real now; Oval distinctly recalled what it was like last night, when neither of them could stop themselves from fucking. How close was he to that state of mind? How much more flirtation would it take for him and Dash to lose themselves in a frenzy of lust and growth?

Rather than find out, they finished their meals in relative silence and went their separate ways with no more than a hug.

Oval Office and Rainbow Dash started the next day with the best of intentions. Waking up alone, they showered their tall, powerful, sexy bodies without giving in to temptation. Dash struggled in particular; she found herself fantasizing about sharing the shower with Oval Office, soaping up his strong shoulders and his washboard abs… and tempting him with her body, inviting him to fuck her in the steamy shower stall.

Even as she drove thoughts of Oval Office from her mind, Dash couldn't help but be turned on by her own body. Running soapy hands over her breasts, she felt a thrill shoot through her, a tantalizing sample of the pleasure her body was capable of. Touching her nipples made her pussy twitch, and she feared that it would be enough to set off a surge of growth - but luckily it seemed to have no particular effect.

Soaping up her ass was also an ordeal. Like her tits, it was a part of her body that had grown far more than the rest of her - and that seemed to have made it a hotspot of sensual pleasure. Those perfectly round blue cheeks, yielding at the touch of her hands, seemed to electrify her cunt, making her whimper and groan in frustration.

With a surge of willpower, Dash turned the shower’s knob, turning the hot, steamy flow into an ice-cold blast. And although her new body was built for pleasure, and seemed to delight in any stimulus… it still didn't like being assaulted by frigid water. Her immense libido shrank back to a manageable size, and she toweled herself off, shivering, and got dressed for school.

She didn't see Oval before the first bell at Canterlot High, but she couldn't avoid him at second-period history. And as luck would have it, the only seat left when she made it to class was right next to him.

She used to be glad to sit next to Oval… and part of her still was happy about it. But that was the part of her that she was trying to keep under control. Her pussy was a powder keg of growth… wonderful, dangerous, destructive growth… and it pulsed with arousal at the sight of Oval Office.

Oval and Dash traded glances throughout the class, admiring each others’ bodies for mere seconds before tearing their eyes away. Rainbow Dash noticed Oval’s dick getting hard, just like it had the first day she’d grown… but since that day, his dick had grown into a long, thick, meaty beast - and the bulge it created as it stiffened was impossible to miss. Turning her eyes upward, she saw the discomfort in Oval’s face as he squirmed in his seat, trying to work his cock into a more comfortable position. It looked like torture; Rainbow Dash knew that her boyfriend’s dick wasn’t meant to be imprisoned within constricting jeans. It was meant to stand free in the open air, proudly extending from his tall, toned bod. Ideally, it was meant to stand out from a skyscraper-sized body, protruding a hundred feet out and casting a long, girthy shadow. And the only thing that should ever contain it should be the immense, godlike womanhood of Rainbow Dash.

Back in reality, Dash felt her pussy growing slick and hot, and she dug her fingernails into the palm of her hand. A little pain was enough to prevent her fantasy from going any further... for the moment. The rest of the class was a repeating cycle for both Dash and Oval - they would each drift into their respective fantasy worlds, then snap themselves out as their arousal spiked to worrying heights.

When the period ended, they both rushed out of the classroom in different directions. Dash managed to move more quickly - not simply because of her natural speed, but because Oval Office had a boner to contend with. His face, normally a handsome blue, was tinted purple by a flush of embarrassment as he covered his crotch with a textbook.

Truthfully, he had nothing to be embarrassed about. An unwanted boner was a classic high school nightmare scenario, but no one else in Canterlot High - maybe no other eighteen-year-old for a hundred miles - had a dick that compared to Oval’s. The other girls in the class didn’t quite know what to make of Oval’s recent growth (most likely, many had correctly drawn the conclusion that it was related to Dash’s), but there was no denying that it made him, like, world-class hot.

During class, Dash had noticed that she wasn’t the only girl who couldn’t keep her eyes off of Oval Office. And the old Rainbow Dash, the one with A-cups and no ass to speak of, would have been threatened by all that attention being focused on her boyfriend. But becoming a sex goddess had sent her already healthy self-esteem into the stratosphere. No one could compare; no girl had her huge, firm tits or her perfect bubble butt. There were a couple who almost had her proportions, but Dash was like a scaled-up version of them. She was - at a rough estimate - twenty percent bigger. And she knew now: Oval Office liked it big.

Of course, Oval Office wasn’t the only one getting admiring looks. As Dash walked the halls of Canterlot High, she turned plenty of heads herself - some male, some female. And that was nice. It was good for the ego. But Dash didn’t anticipate being tempted by any other guys; her body deserved the best. She needed to be held by strong arms and filled by a cock long and thick enough to touch every inch of her inner walls.

Dash and Oval still didn’t share many classes, so it was easy to avoid him for the rest of the school day. And the track team had practice today; hopefully some vigorous exercise would help her blow off steam and keep her mind off sex.

But when she showed up to practice, she was confronted with something she couldn’t believe she’d forgotten. Applejack, loitering around the shot put circle, was also the beneficiary of the magical potion that had turned Oval and Dash into giants. And like the two of them, she hadn’t been shrunk all the way back to normal size. She was just as tall as Dash, just as busty, with an ass every bit as round…

Granted, this was an improvement over the way things had been. Throughout most of their friendship, Applejack had been far more developed than Rainbow Dash, and Dash had been quietly jealous for years. That jealousy had turned red-hot when the two of them began to compete for Oval Office’s affections… and, of course, that had resulted in their enormous, destructive three-way two nights ago.

But when all was said and done, Dash and Applejack had ended up at the same size. And Dash could live with that - especially since she was the one who ended up winning Oval Office’s heart.

So there was another girl at Canterlot High who could compete with Dash’s physique. A pang of fear stabbed at Dash’s heart, but only for the briefest of moments. Oval Office was a stand-up guy - and Applejack, who was honest to a fault, had agreed that Dash had won Oval fair and square. And with a body like that, Applejack would have plenty of guys to choose from.

But at the moment, she didn’t seem pleased.She was pensively holding a shotput, testing its weight in her hand, as Dash approached.

“Hey AJ!” called Dash, and Applejack turned to her, brightening at the sight of her friend.

“Howdy Dash,” she said. “Sunset tells me you’re havin’ some trouble with some, uh… aftereffects?”

“Yeah,” said Dash. “I can’t… cum… or else I’ll get big again.” Something clicked in her head. “Oh! What about you? You gotta keep your hands off yourself too?”

“Well… ‘parently not,” said Applejack. “After Sunset figured out what was happenin’ to you an’ Oval, she had Twilight drive out to my place an’...” She trailed off, a blush darkening her freckled face. “Well, we had ta know if I was affected in the same way, so she came an’... observed… while I touched myself.”

“And?”

“Well… I made it to… completion,” said Applejack. “And… nothin’ happened.”

“Seriously?” said Dash. “That means… uh… what does that mean, exactly?”

“Well, Twilight reckons that you got that potion first-hand, and Oval got it second-hand… and me gettin’ it third-hand is just enough to keep me from bein’ affected.”

Dash chuckled. “Third-hand” was an adorably polite euphemism for how the effects of the magical potion had been passed along. Oval had gotten it from eating Dash’s pussy, drinking deeply of her fluids… and Applejack had gotten it when Oval Office’s big blue cock had smashed through her roof and flooded her bedroom with jizz.

“Well, that’s lucky,” said Rainbow Dash. “Oval and I have to keep our hands to ourselves until Sunset and Twilight figure out an… anti-potion… but you can just put all this behind you and enjoy your big sexy body.”

Applejack’s expression turned pensive again, and she tossed the heavy shotput up into the air - way up into the air - and caught it effortlessly as it came back down. “Yeah, maybe,” she said. “But… I ain’t sure if it’s totally fair fer me to compete in sports, what with bein’ magically big ‘n’ strong.”

“Oh,” said Dash. “Yeah, that’s… hmm. Well, let’s figure that out later. Right now I just need to focus on anything that isn’t sex.”

A small, grassy hill overlooked Canterlot High’s track, providing a pleasant spot from which to spectate. In the past, Oval Office had come here after school to do some reading, enjoying the sun and occasionally lifting his head to watch the feats of athleticism down on the track. In fact, this was how he got to know Dash and AJ - in time, he’d come down to spectate them more closely, admiring them and getting to know them better.

But today he was back on the hill, watching from afar - because he knew that he shouldn’t be here. He should be driving home, thinking about history and mathematics and other dry scholarly pursuits. Not watching Rainbow Dash’s perfect body dominate the track.

But he couldn’t help himself. He was worried about Rainbow Dash, who was beautiful and strong and bold… but also dangerously impulsive. Oval loved her, but if she had any self-control then she wouldn’t have gotten herself and Oval into this whole mess.

But of course that was just an excuse. A flimsy justification for Oval Office to come out to the track and watch his beautiful girlfriend. The truth was, Oval himself had less self-control than he gave himself credit for - at least when it came to Rainbow Dash.

He arrived just in time to see her start the hundred-yard dash. The other girls cast nervous glances at her as they knelt in the starting blocks, unsure of what to expect from their enlarged teammate. Come to think of it, Oval wasn’t sure what to expect either; Dash’s new body was strong and nimble in the bedroom, but its curves didn’t seem to be built for track and field. There was a reason why Dash’s slim body had been ideal for running… and why young women with massive breasts didn’t typically dominate footraces.

But when the rubber hit the road, so to speak, magic triumphed over physics. Rainbow Dash exploded out of the blocks, her long blue legs propelling her forward with unreal speed. Her breasts, despite being bigger than the other girls’ heads, stayed firm on her chest. Oval had seen those breasts jiggle, when Dash had stuck out her chest seductively… but right now, when she needed them to behave, they were staying out of her way. Magic really was incredible.

Dash, crossing the finish line at full speed, was even more astonished at her miraculous chest. After she slowed to a stop - barely sweating and not short of breath, she realized - she tried hopping a few inches off the ground. When she hit the ground, her tits jiggled like two queen-sized servings of flan… but they’d been absolutely still while she was running. “Holy shit,” she gasped, openly groping herself through her white t-shirt. “You two and I are gonna get along just fine.”

Dash hadn’t anticipated that her body would have even more wonderful surprises in store, and the discovery sent a thrill down her spine… all the way down to her pussy. Simply feeling her sky-blue boobs jiggle was a huge turn-on, and groping them only amplified it. As soon as her fingers sank into the warm, pillowy flesh, Dash’s curiosity instantly transformed into lust - and she couldn’t take her hands off herself.

Dash told herself that she was just examining herself, getting a feel for the gorgeous magical globes on her chest. As long as she wasn’t touching her pussy, she told herself, she wasn’t at any risk of growing. But sex was already beginning to consume her mind, and a tiny part of her mind started to think that maybe, just maybe, it wouldn’t be so bad to touch herself right here. On the track. In front of everyone.

After all, they were already watching what she was doing to her tits, right? She was already embarrassing herself, looking like a sex-crazed slut in front of the whole team. What kind of girl played with her boobs in public, helplessly kneading her soft mounds where everyone could see her? They already knew what kind of girl she was… fingering her wet slit could hardly make things worse.

And come to think of it… who cared what they thought of her? As soon as she started touching herself, she’d begin to grow. These tits, these marvellous tits would tear her pathetic shirt to shreds as they expanded. Her stretchy gym shorts would last only moments longer before her ass ballooned too big for it to contain. Naked, her body soaring past twenty feet, she would flick and stroke and penetrate her womanhood until fluid streaked down her towering legs. And once she came, she would surge with growth, perhaps hitting a hundred feet, her fingers flicking sweet liquid onto the tiny track team. Then she would stride across campus, leaving wide footprints in Canterlot High’s lawn, seeking out her boyfriend.

Oval Office, his cock stiffening as he watched Dash grope her tits, had a parallel fantasy. Dash seemed only moments away from sticking her hand down her gym shorts, and if that happened… well, he couldn’t let her grow alone. He’d have to join her on the track, rubbing at his crotch through the fabric of his pants, and plant a kiss on her moaning lips. They’d hold the kiss for a moment, tongues wrestling, tasting each others’ mouths… but soon they would begin to undress one another.

They would start gentle, of course, but lust would erode their patience. They would begin to tear at each others’ clothes, using their enhanced strength to rip the flimsy fabric away. Bare, with the track team watching, he would slip his hands beneath Dash’s round blue bottom and lift her up - then lower her down onto his cock. Standing, embracing, they would fuck. Oval’s hands would explore Rainbow Dash’s body, tracing her curves and feeling them grow under his fingertips. Dash would stroke Oval’s arms and his back - and then find her way down to his marvellously toned ass. Together they would grow, their bodies overshadowing the track, then the school… and when they came, their cries would shake all the windows in town.

And their fantasies were coming dangerously close to becoming real. Dash sent one hand creeping downward, below her bust, past her belly button… And then Applejack caught her by the wrist, holding her hand in place.

“Dash!” she hissed, “Y’all can’t do that!”

“Shit,” gasped Rainbow Dash. “Sorry. I couldn’t help it…” Applejack’s tight grip on her wrist was enough to snap Dash out of her sexual trance, and she took her other hand off her chest.

“This is gonna be really difficult fer ya, ain’t it?” Applejack sighed. “Do ya need my help?”

“Yeah, I think so,” said Dash, hanging her head.

Up on the hillside, Oval Office was shaking off his sexual daydreams as well. He naturally possessed a bit more self-control than the impulsive, spunky Rainbow Dash, so the mere sight of Applejack intervening in Dash’s self-love was enough to cool him off. Of course, his fantasies had left him with a prominent hard-on… and his magically enhanced dick was slow to go back down after it became hard. Shifting his boner into as comfortable as a position as he could get it, he stayed seated on the grassy hill, trying to clear his mind as his erection subsided.

But a voice made him turn his head - and he saw Applejack and Dash climbing the hill as they left the track. “Darnit! You too, huh?” said Applejack, striding over to him with Dash following behind. “Lemme guess, Oval. You came out here to ogle Dash, even though you knew the smart thing to do was avoid her as long as possible. That sound about right?”

“...Yeah.”

Applejack sighed. “You know we’re countin’ on the both of y’all to stay away from temptation, right? Now, I know you two have it harder that me, and, hell - maybe you’re tryin’ your best. But I’m startin’ to think yer best ain’t good enough. So I’m assignin’ myself as yer chaperone. I’ll make sure you two keep some distance between yerselves… and I’ll be there to slap yer hands away from yer junk when I need to.”

“Yeah,” said Rainbow Dash, “For real, I don’t know if I can make it through the rest of the day without help.”

“Well all right then,” said Applejack. “Dash, yer comin’ with me, we’re gonna shower up and meet Oval Office outside the gym.” She turned to Oval Office. “Oval,” said Applejack, “Yer job is to forget I mentioned anything about showerin’.”

She led Dash away by the hand. Oval, still trying to get his cock to go down, tried to think about baseball.

“You were right, AJ,” said Rainbow Dash, resting her chin in her hand, “This is awful.”

“Well, I wasn’t commentin’ on the artistic merit,” said Applejack. “I was just thinkin’ it wouldn’t be arousing.”

On the way to her car, Applejack had looked up possible activities on her phone. With her authority as chaperone, she decided that the three of them were going to see Dark Corridor, a horror movie that had been unanimously panned by critics and crowds. Not scary enough to raise anyone’s heartrate, not bad enough to be funny, with an audacious one hundred and forty minutes of runtime. It sounded absolutely mind-numbing - and with any luck, it would also numb the lovebirds’ libidos enough that they could get through the night without sex.

“But yeah,” said Applejack, her eyelids drooping, “it is pretty bad.”

The movie was in the third week of its theatrical run, and word of its quality had gotten around - so aside from them, the theater was completely empty. An empty theater could be a dangerous place for two horny eighteen-year-olds who needed to avoid temptation, but Applejack was occupying the seat between Oval and Dash. As much as their bodies wanted it, they weren’t going to be able to sneak any hanky-panky past Applejack.

And the awful film was doing its job pretty well. In the dark theater, neither Oval nor Dash could get a good look at the other one’s body. Applejack’s stern supervision discouraged them from touching themselves, and so there was nothing for them to focus on but the film. By the two-hour mark, all three of them were bored and miserable - but they weren’t thinking about sex. Applejack was squirming in her seat… but not for sexy reasons. And when she couldn’t take it any longer, she stood up and turned to address her friends.

“All right,” said Applejack, speaking over the film, “I gotta use the ladies’ room. I don’t feel great about leavin’ you two alone, but I’m at my limit. I’m trustin’ y’all to behave yerselves fer like five minutes, all right?”

They nodded, and Applejack left the theater.

They sat in silence for about half a minute, respecting the unoccupied seat that Applejack had placed between them. Finally, Rainbow Dash spoke.

“Hey, Oval,” she said, “I know this is all my fault, and… I don’t even know if I apologized to you. But I’m really sorry.”

“You’ve apologized enough,” said Oval Office. “I’m glad we’re together, and… hopefully we’ll be able to put this behind us soon. Your friends will make a cure, and we’ll get to be a normal couple.”

Dash scoffed. “Normal, huh? Well, if it’s with you… I’ll take it.”

Smiling, Dash turned back to the movie screen. But the scene had changed abruptly while they had been talking, and now it showed a woman waking up to discover that her bedroom was shrinking all around her.

At least, that had probably been the director’s intention - and in more capable hands it could have been an effective horror sequence. But Oval and Dash looked at the scene and saw growth. They saw a beautiful woman growing larger, outgrowing her bedroom - and their snoozing libidos awoke instantly.

“Oh, shit,” groaned Dash, groping her tits with both hands. “I was wrong, this movie kicks ass.”

By the light of the screen, Oval could see Dash groping herself - and only then did he realize that he was stroking his inner thighs, his fingers dangerously close to his stiffening cock. There wasn’t even anything arousing on the screen anymore - the film had moved on to the next unremarkable scene - but that little spark had lit a blaze inside him, and it would take a concerted act of willpower to put it out.

But Dash wasn’t about to give him the chance. As he looked at the screen, a dark shadow blocked his view and descended onto him. Then the world went completely dark as his head sank into the softest flesh imaginable. Dash was smothering him with her tits, pressing her chest against his face. He could still breathe, but only barely - and the air that entered his lungs was scented with the sweet fragrance of Rainbow Dash’s skin.

“I gotta grow, Oval,” moaned Rainbow Dash. “I gotta fuck, my pussy’s so fuckin’ wet… I don’t care what happens, I don’t care if we smash up the theater or the city or the whole fuckin’ world…” She jammed her hand down his pants, grasping his shaft. “I need this, Oval. I need you to fuck my pussy and suck my titties and make me big.”

Oval felt Dash working his fly open, freeing his dick. “Just let me ride this beautiful cock, Oval,” she groaned, stroking his shaft into full hardness. “We’ll fuck til morning, and every time we cum our perfect bodies will get bigger and bigger… I’ll have tits bigger than mountains and you’ll have a cock that could knock the fuckin’ moon out of the sky…” Her tits, still covering Oval Office’s face, rose and fell with deep heaving breaths. “Just say yes, Oval. Just say you’ll fuck me so we can be gods.”

“Oh, fuckin’ come on!” shouted Applejack, stomping up the steps to the row where Dash was seducing Oval. Growling, Applejack grabbed Rainbow Dash by the shoulders and yanked her away from him.

“Dash, what the hay am I s’posed to do with ya?” demanded Applejack, her voice just barely below a shout. “Maybe I was wrong to think this was a one-woman job.” She sighed, pulling her phone out of her back pocket. “All right, who ain’t busy? Maybe Pinkie or Rarity has time to babysit ya, Dash?”

She tapped at her phone for a short time, then frowned silently as her texts went unanswered.. “You know what? Forget it. I can handle this. Oval, put yer cock away, we’re goin’ for a drive.”

Gravel roads gave way to dirt as the car ride entered its third hour. Applejack and her two passengers drove into the night, barely exchanging a word. As soon as they’d gotten in the car, Applejack had started playing a true crime podcast through her car’s speakers at a jarring volume, and Dash and Oval had taken this as a hint that she wasn’t in the mood to talk.

And so Rainbow Dash and Oval Office, shamed into silence, had no idea where Dash was taking them. It was dark, and the territory was unfamiliar; Oval saw dense trees and the reflection of the moon in the surface of a lake, but those weren’t exactly concrete landmarks.

And finally, just as the podcast was approaching a revelation that Oval was genuinely looking forward to, Applejack stopped the car. “All right,” she said. “Oval, get on out. You’re stayin’ here tonight.”

“Here?” said Oval, stepping out of the backseat and trying to make out any shapes in the moonlight. He couldn’t actually tell whether there was a “here” here - but when he looked in the direction Applejack was facing, he saw a modestly sized but modern house, tucked away between the trees by the lake.

“Yeah, this place is Rarity’s,” said Applejack. “Her dad’s, anyway. I think he was hopin’ fer boys… or at least a couple of more outdoorsy girls.” She sighed. “Uh, don’t tell Rarity I said that, all right? It’s been a long day an’ my trademark honesty is sorta on autopilot.”

“Okay,” said Oval. “So why am I staying here?”

“Because I trust ya more than I trust Dash,” said Applejack. “I’m takin’ her back to the farm to keep an eye on her. You’ll stay here and not jerk off. An’ if ya can’t help yerself… just get outside before ya get too big, okay? I’m pretty sure this place is insured, but I’d rather ya leave it intact. We’re all comin’ up here tomorrow fer a get-together.”

“Oh,” said Oval. “So I won’t be alone here too long, then?”

“Nah, Dash probably woulda invited you up, if things weren’t so weird. So yer just gettin’ here a little early. Plus it’s actually real nice. I’ll give ya a quick tour.” She led the way to the front door, taking a spare key from her pocket.

“And… you trust Dash enough to leave her alone in the car?” asked Oval.

Applejack sighed wearily. “I don’t enjoy bein’ cross with Dash,” she said, “And I haven’t forgotten how good it felt to be growin’... and how none of us were even thinkin’ about how maybe we should stop. Dash ain’t got it easy right now, an’ neither do you… but I’m over here bustin’ my hump and it ain’t exactly a picnic.”

Applejack let Oval Office in, checked on the water and the electricity, and showed Oval a first-floor bedroom. “Don’t worry about me an’ Dash,” she said, forcing a smile. “We’ve been through worse. Tonight, you just try not to touch yerself… and who knows! Maybe when all the girls come to the lake house tomorrow Twilight’ll have a cure for ya!”

“I hope so,” said Oval. “Once this is all over… we’ll make it up to you somehow.”

Standing in the doorway, he waved goodbye to Applejack. He turned his eyes toward the car, where Dash was miserably slumped in the passenger seat, and waved in her direction too. She returned the gesture feebly, and they kept their eyes on each other until Applejack turned the car around and drove out of sight.

Oval paced the lake house for a while, making himself a dinner of granola bars from the kitchen’s stock of non-perishable food. He grabbed a book blindly from a shelf in the living room, opened it somewhere near the middle, and flopped down on the bed.

There was still a mild pressure in his crotch, an insistent need for release… and just like Applejack had said, it wouldn’t be too terrible if he grew out here. The nearest house was miles away; if he stepped outside, cranked one out, and grew to ten or twenty feet tall, there wasn’t much around for him to destroy.

But being quarantined by an angry Applejack had kind of killed the mood for him. Fully clothed, he pulled the bed’s covers over himself and closed his eyes, trying to fall asleep as quickly as possible.

Oval woke up to the sight of his morning wood tenting the thick covers. He experienced a brief moment of panic, imagining that a wet dream might have triggered a round of growth - but the bedroom around him was normal-sized, his clothes still fit, and he hadn’t soaked the sheets with jizz.

He considered skipping his morning shower - his erection wasn’t going away, and stripping down and slicking up seemed like a risky prospect. On the other hand - he did just sleep in his clothes, and sometime today a bunch of girls would be coming over. He decided to risk it, keeping the water as cold as he could comfortably bear. In the bedroom’s dresser, he found a clean flannel shirt that must have belonged to Rarity’s dad, and found it to be a pretty good fit.

And after that, there wasn’t much to do but sit on the deck and stare at the lake. Reclining in a deck chair, watching the water ripple gently, Oval Office started to see the appeal of a secluded living space. It was calming - and while Oval still had a hard-on, unable to shake the morning wood he’d woken up with, his mind was mostly clear of dirty thoughts.

But even in his meditative state, he couldn’t resist checking his phone every so often - even though the first look had showed him there was no cell service out here. He desperately wanted to get a status update on the cure from Twilight and Sunset, but until they showed up he’d have to stay in the dark, with a boner poking up past the waistband of his pants.

When a car engine broke the silence, Oval leapt from his seat and raced through the house, throwing open the front door to greet the girls. They’d arrived in a car he didn’t recognize - although since Rarity was driving he took it to be hers - and they piled out, pulling coolers and overnight bags from the trunk. Rarity, Pinkie, and Fluttershy were the first to leave the car, and they greeted him with varying levels of enthusiasm as he approached.

Sunset and Twilight, Oval noted, were conspicuously absent from the car - although there would scarcely have been anywhere for them to sit, with Applejack and Rainbow Dash occupying so much of the back seat. Their asses, two big round bubbles of equal width, must have left little room for Fluttershy.

Applejack emerged first, taking a long swallow from a tall cup of coffee. She was bleary-eyed, leaning weakly on the car despite the strength and size of her body. Rainbow Dash, on the other hand, looked great - and once she saw Oval Office, she spread her arms and stepped forward to embrace him.

But Applejack threw out an arm, her reaction time much better than her weary body language suggested, and caught Dash before she could get to Oval. “No hugs,” she muttered, and took another chug of her coffee.

“Oh come on!” said Dash. “Not even a hug? Come on, you can just tackle me if things get too steamy.” Dash’s pouty face was adorable - especially contrasted with the outrageously curvy body it was attached to. Oval’s sense of isolated serenity was shattered by the sight of Rainbow Dash - the girl with the unreal body, the girl who desired him just as much as he wanted her. If they did hug, Oval was pretty sure AJ would have to tackle him; feeling Rainbow Dash’s body against his would just overwhelm his defenses.

“Sunset an’ Twilight are on their way,” said Applejack. “Y’all ain’t gotta wait much longer for yer cure, and once you get it the two of y’all can find a bedroom an’ go nuts on each other. Til then, takin’ risks is just damned foolish.”

“Yes, thank you for volunteering one of the bedrooms in my family’s lake house for Dash and her boyfriend to fuck in,” said Rarity. “When I gave you that spare key, I was hoping you’d turn the place into a love motel.”

Applejack just shrugged.

“I was only joking, darling,” Rarity apologized. “Of course it’s fine. And I should have known you wouldn’t be in the mood for jokes, after getting no sleep at all last night.”

“Applejack watched Dash all night!” said Pinkie. “Just to make sure nothing naughty happened…”

“Yeah, and nothing did happen,” said Rainbow Dash. “Applejack was so sure I was gonna touch myself, or just come in my sleep, and it was fine.”

Applejack’s expression darkened, and Dash rushed to correct herself. “But, uh, I appreciate that you sacrificed a night of sleep to keep me safe. You’ve been a good friend throughout all this, and I’ve been… less good.” Oval’s heart sank when he saw Dash’s dejected expression - Applejack was probably right, and their friendship had been through worse, but right now they were both feeling the strain.

“Thanks, Applejack,” said Oval. “We owe you a lot.”

“Just doin’ what needs doin’,” said Applejack. ‘But if y’all feel like makin’ it up to me, I’m sure we can figure out some kinda - oh thank heavens.”

Applejack dropped the arm she’d been holding up between Dash and Oval, and she slumped against the car, her enhanced bust wobbling as she slid down onto her butt. Dash and Oval turned to look where Applejack had been facing - and they saw Sunset pulling up to the house with Twilight in the passenger seat.

Oval and Dash broke into a run, almost throwing themselves onto the hood as Sunset and Twilight calmly exited.

“You have the cure?” asked Oval breathlessly. Twilight stepped back, a little intimidated.

“Er, yes,” she said. “We finally cooked it up this morning, and we both feel really good about the results! But in case it needs any tweaking, we’ve got the mobile lab in the trunk-”

“So we can take the cure?” asked Dash. “And we can have sex?”

That’s probably the best way to test it,” said Sunset. “Now, the spell is in tablet form now, and you will want to chew it. Once you’ve swallowed it, you should be good to go.” She pulled an orange pill bottle with a ripped label from her pocket, dropped two pills in her hand, and held them out. Oval and Dash each grabbed a tablet, chewed hastily, swallowed… and turned to Sunset expectantly.

“You should be fine now,” said Sunset, shrugging. “Have fun, I guess.”

Rainbow Dash and Oval Office turned to each other, taking in heavy breaths as they looked over each others’ bodies. Oval had done his best not to look directly at Rainbow Dash since she stepped out of the car, but now he really let himself see her. Her wide magenta eyes, framed by rainbow bangs. Her pale blue lips, smiling hungrily between flushed cheeks. Oval Office had started to fall in love with that face even before their first date and the whirlwind of sex and growth that followed. And it was just as beautiful now - but it sat atop a body that was unreal.

Dash’s chest was heaving with each deep breath she took. Those tits, those big blue melons that Oval had cradled in his hands, squeezed and teased and pinched, were just inches away from him. And then there was her ass, even bigger and wider than her bust, squeezed tight inside her jeans. Even fully clothed, she seemed almost naked, her enormous assets ready to burst out of her tight top and snug pants.

Over the past couple of days, he’d become scared of his own sex drive. He hesitated to even touch Rainbow Dash, imagining the growth and the destruction he’d been trying to avoid. But now he was cured. He was free. And nothing ever needed to come between him and Dash again.

He took Dash by the shoulders - surprised to be making the first move for once - and pulled her into a kiss. From the first moment, the kiss was passionate, lustful, almost pornographic - Oval and Dash were devouring each other, their slick tongues wrestling amid rising moans. Their hands were every bit as busy, groping and pulling at each others’ clothes - Dash unbottoned the flannel shirt Oval had borrowed, tossing it into the dirt after she pulled it off him. Oval lifted Dash’s top, and they broke the kiss momentarily to get it past her head. Her enormous tits wobbled in the sunlight for a moment - and then Oval and Dash embraced again, and the big blue mounds were smushed between their bodies, rubbing up against Oval’s chest as the two lovers kissed deeply.

“Um… are you just going to do it out here?” asked Fluttershy meekly. “Should we go inside?”

“Mmmph… maybe,” whispered Dash, briefly pulling back from the kiss before diving in again, “Maybe we should… find a bed…”

Oval grasped Rainbow Dash’s hand, intertwining their fingers, and he led Dash inside the lake house. When they made it to the bedroom Oval had slept in, Dash threw herself onto the bed and began to peel her jeans off, freeing her big blue bubble butt. Looking up at Oval with half-lidded eyes, she stroked a finger down from her tits, past her belly button, and finally to the waistband of her pink panties.

But Oval was too horny, too hungry to just passively observe as Dash stripped herself. He crawled onto the bed and leaned his face into her crotch, breathing in the scent of her skin… and her wet womanhood. Baring his teeth, he pulled her panties down, slowly exposing those slick lips, freeing a bouquet of strong, sweet sexual musk. His cock pulsed with arousal, leaking a thick drop of precum - and when he extended his tongue and parted her folds, the taste of her pussy made his manhood throb once again.

“Oh, you’re ready for this,” moaned Dash. “Fuck, I feel like I’m gonna explode…” Oval licked the way around her lips, then flicked at her clit, making her legs kick involuntarily. “Aw shit, Oval, I’m gonna… you gotta stop… I don’t wanna cum without you, I don’t wanna cum without your cock inside me… please, just fuck me…”

Oval could have stayed down there, tasting Dash’s pussy, feeling her squirm beneath him. But now that she was begging to be fucked, he couldn’t deny her what she wanted. He lifted his head and stripped away his pants, freeing his cock.

“Oh fuck, it feels like forever since I saw that dick,” said Dash, grabbing one of her tits and kneading the soft flesh. “So big and so fuckin’ hard, how do you keep your hands off that thing? I swear, Oval, now that we can fuck anytime we want, I’m gonna be grabbin’ that cock… suckin’ that cock… riding that fuckin’ cock every chance I get.” She whimpered, throwing her head back. “I’ve waited so long, I’ve been so good, please just gimme that dick…”

Oval climbed back onto the bed, grasped Rainbow Dash by the shoulders, and eased himself into her. “Aw, how did I live without dick?” groaned Rainbow Dash. “Fuck, if I knew it would be this good, I woulda made myself cum til I was… fuckin’ five hundred feet tall… then torn the roof offa this lake house... so I could suck off my handsome little man til he grew big enough to fuck me.”

“You feel incredible,” said Oval, pumping his full length in and out of her. “Oh, you’re perfect… there can’t be any pussy better than this…”
“I know one thing that would make it better,” said Dash. “If I was the size of a skyscraper, and you rammed my cunny with a dick bigger than a fuckin’ freight train. That’d be even better, huh?”

“Well…” gasped Oval Office, “I mean, we just put a lot of work into making that not happen…”

“Totally,” said Dash, throwing her arms around him, stroking the muscles of his back. “But now that we’re not gonna grow, we can still think about it… I can still talk dirty about how I wanna see your gorgeous toned ass knock over some buildings…” She clapped her hands onto his ass, massaging his glutes with her fingers.

“I guess so,” said Oval. “I mean… I liked watching you grow… and I liked being big… I guess it can be our fantasy from now on.”

“Yeah, that’s the spirit,” said Dash. “I can be your big girl, and you can be my strong, sexy giant… but you gotta fuck me like a giant. How would you fuck if you had a fifty-foot cock, Oval?”

“I guess I’d fuck hard…” grunted Oval Office, “and fast...” He pumped his hips faster, and Dash moaned and clutched at the sheets. “I’d go fifty feet deep in that big wet giantess pussy…”

Dash gritted her teeth, grinning as Oval got into it. “Aw fuck yeah, that’s my big sexy man,” she growled. “Swingin’ that big fat cock, bringin’ down whole cities…”

Dash’s hands grasped Oval’s waist, and with a burst of strength she rolled the two of them over. Before he knew what was happening, Oval was on the bottom, with Rainbow Dash staring down hungrily at him.

“This is what the tinies see,” said Dash, shaking her body to make her tits wobble. “All those little people who aren’t big and beautiful like you and me.” She bobbed her body up and down, riding his cock with growing speed. “When Rainbow Dash the fucking goddess comes to their city. Goddess of victory and beauty and size. They look up at my smiling face and they worship my tits… some of ‘em pray to be spared… some of ‘em beg to be crushed under my boobs…”

She really did look like a giantess from down here, thought Oval. A dangerous, fickle goddess of size… but she was his, and he was just as big, and they would shake the earth with their lovemaking…

“Shit, Oval, I’m close,” gasped Rainbow Dash. “Are you close? I wanna feel that skyscraper cock hittin’ me with an ocean of cum…”

“I’m close,” said Oval. “I’m gonna cum… any second…”

“Yeah, let’s do it, let’s cum together,” groaned Dash, bouncing on his cock with all the strength in her hips. “I just need one thing, Oval, you gotta tell me… you gotta tell me if I’m big.”

They weren’t growing; the bedroom around them was the same size, the walls no closer than before. But Oval felt big. At any size, Rainbow Dash’s love and the embrace of her body was enough to make him feel a thousand feet tall. “Oh yeah,” he said, “You’re big, Rainbow Dash. You’re bigger than anyone, and you’re getting bigger…”

Dash’s hips slammed down onto Oval Office’s cock, slapping his skin with her wide blue bottom. Her body tensed, and her pussy clenched, and she raised a cry to the heavens as she came. Oval, his cock held tight in her cunt, felt his balls tighten as her walls milked his shaft insistently - and within seconds he joined her in climax, his cock shooting harder than it had ever shot before.

And it felt so good, so impossibly, rapturously good - in fact, it was too good. It shouldn’t have been possible for a climax to be so intense - but Oval realized that he’d felt this before. This is how it felt to grow. Looking up, past Dash’s head, he saw that the ceiling was closer than before. He kept his eyes on it, expecting to see it creep closer...

But just as the next throb of climax hit, he and Dash surged with growth, so much growth that her head hit the ceiling. “-the fuck?” she grunted, looking up. “Are we…” she looked around, seeing the same thing Oval saw. The room had closed in, leaving almost no space for the two growing lovers - and Dash felt her pussy starting to throb with climax again. “No, we can’t-” she gasped, “We have to stop-”

But there was no stopping. This wasn’t like last time, when they grew as they made love - they’d stayed at the same size until the onset of climax and now they were growing all at once. Last time they grew because they couldn’t control themselves, because they couldn’t stop themselves from fucking - but now they really couldn’t stop. Even with perfect self-control, there was no stopping an orgasm.

Their bodies rode out the climax in unison - Dash’s pussy clenched, and Oval’s cock shot another load - and their orgasms sparked another surge of growth. There was no space left in the little bedroom, so they outgrew it, bursting through the walls, punching through the ceiling, turning plaster and wood to powder and splinters with the unstoppable growth of their bodies.

Luckily for the lake house, the little bedroom was tucked into a corner of the first floor. The structural damage, as their twenty-foot-tall bodies tumbled out of the house, was immense - but it wasn’t so bad that the whole structure collapsed.

Another surge of growth hit them, and Oval felt his spreading shoulders pushing aside the trees beside the lake house. “Oval,” groaned Dash, “We’re so big…” Oval Office couldn’t tell if Dash was happy or sad about it - and he wasn’t sure how he felt about it either. They’d both fought so hard to prevent this… and yet, it was the greatest feeling in the world.

Each burst of explosive growth was bigger than the last, and the next one stretched Oval’s legs so far that his heels were dipping into the lake. Dash was still on top of him, riding his cock, groping her expanding tits. He was lying flat, but she was sitting up straight on his crotch, her head climbing towards the sky with each surge. There was nothing above her but sky now.

From the tip of his ten-foot-long cock, Oval Office shot gallons into Rainbow Dash’s immense womanhood. They grew past a hundred feet, and Oval could feel that there was more on the way…

A door slammed nearby, and the rest of the girls poured out of the lake house’s front door. Sunset and Twilight looked on in dismay - although they surely already suspected that their “cure” had failed. There was no time to speak - they arrived just in time to see Dash and Oval experience their last - and biggest - growth surge.

Moaning helplessly, the two giants exploded in size. The lake house, or what was left of it, was spared - but beside it, hundreds of trees were knocked flat, crushed beneath Oval’s expanding body. The lake became a puddle underneath him, and he lay back, groaning in pleasure.

Dash, towering above the rolling hills, sent out a cry that spooked birds from their trees for miles around. Her groping fingers sank into the skin of her tits as her orgasm hit is final peak - and then she went nearly limp.

No one spoke for a long time - neither the giant lovers nor the girls watching them. But Twilight Sparkle silently pulled a small notebook from her pocket and began to flip through her notes, looking for errors.
